(another bridge structure body monitoring embodiment)
Figure 10 is another embodiment of structure monitoring and light carving illuminator communication continued access schematic diagram, refer to 8 steps shown in Figure 10 (D) ~ (L), graphic is the right half of part of bridge, utilizes and switches the step signal that master slave mode transmits data.Wherein, D0 ~ the D6 of Figure 10, E0 ~ E6, F0 ~ F6, G0 ~ G6, H0 ~ H6, J0 ~ J6, K0 ~ K6, L0 ~ L6 are the configuration schematic diagram of solar LED (Light Emitting Diode) lamp wireless sensor device on bridge, its position can optionally arbitrary disposition, not necessarily line spread.This is graphic, is only and can knows exposure step, and draw in a linear fashion.Wherein, D7, E7, F7, G7, H7, J7, K7, L7 be can with the communication relay point of world-wide web line, configurable in the two ends of bridge.First refer to shown in Figure 10 (D) and Fig. 1, the longitude and latitude of this solar LED (Light Emitting Diode) lamp wireless sensor device of control module 11 internal memory in bridge installation place and the height coordinate data of Fig. 1; Wireless communication module 11 ' is as during from node, and the data of its broadcast, comprise longitude and latitude and the height coordinate at the numbering (ID) of supervising device point own, supervising device point place place own; When erection completes, each device also stores simultaneously and is arranged at the coordinate that bridge two ends maybe can reach the communication objective many places relay station of transmission, if the D7 in 10 (D) in figure is then the right-hand member relay station of one of them; Wherein the numbering (ID) of supervising device point can be general name, MAC Address or IP address.With regard to bridge monitoring, operation mechanism and the method for the relevant apparatus element of solar LED (Light Emitting Diode) lamp wireless sensor device and system monitoring bridge function are as follows:
Step one, solar LED (Light Emitting Diode) lamp wireless senser are from node: as shown in Figure 10 (D).Each solar LED (Light Emitting Diode) lamp wireless sensor device D0 to D6 be usually bluetooth from node, the sensed values of the 3-axis acceleration sensor reading its sensor is carried out in timing, and judges.The mode judged is according to inner formula, and historical data, relatively with or without abnormal occurrence, the formula of this inside or enquiry form (look-up table) content, by bed rearrangement bridge design load or simulate, assessment is subject to wind-force or earthquake or oversize vehicle etc. when affecting, the due secure data scope of each node.If the three axis accelerometer sensed values having a certain LED wireless sensor device to read exceedes Security alert scope critical value, such as, S1 solar LED (Light Emitting Diode) lamp wireless sensor device D1 in Figure 10 (D).
Step 2, solar LED (Light Emitting Diode) lamp wireless senser host node: as shown in Figure 10 (E).This M1 solar LED (Light Emitting Diode) lamp wireless sensor device E1 converts Bluetooth master node M1 to by from node S1 at once, and the S0 ~ S7 carrying out scanning near interpretation other to surrounding is from node E0 ~ E6.
Step 3, as Figure 10 (F), because of the factor such as radio communication range, interference, when M1 Bluetooth master node F1 obtains the multiple neighbouring numbering (ID) of S0 from node F0, S2 from node F2, S3 from node F3 and S4 from node F4, longitude and latitude and height coordinate from scanning, just can calculate this several distance from the relay station node and record, comprising S/WiFi relay station F7, as as shown in Figure 10 (G), and to draw with the distance of S/WiFi relay station G7 with S4 from node G4 to be nearest.
Step 4, as shown in Figure 10 (G), at M1 Bluetooth master node G1, learn nearest from node G4 with S4 to S/WiFi relay station G7 after, start to carry out the connection of S4 from node G4, and to the abnormal sensing data of its write circular.
Step 5, as shown in Figure 10 (H), by M1 Bluetooth master node G1 write S4 be converted to M4 Bluetooth master node H4 at once from node G4.
Step 6, as shown in Figure 10 (J), M4 Bluetooth master node J4 repeats step 2, step 3, when discovery can be directly connected to S/WiFi relay station J7, and until abnormal data to be sent to S/WiFi relay station J7, as shown in Figure 10 (K).
Step 7, as shown in Figure 10 (L), receiving the S/WiFi relay station L7 of abnormal data, transferring data to Master Control Center by being responsible for, complete each solar LED (Light Emitting Diode) lamp wireless sensor device master-slave swap, transmit data object; If S/WiFi relay station L7 damages, when finishing the work, transmitting data will increase the information comprising and damage relay station.When each solar LED (Light Emitting Diode) lamp wireless sensor device is in master-slave swap process, find that there is the information damaging relay station, by revising the information of relay station, looking for other nearest bang paths, having continued data transmission work.When each solar LED (Light Emitting Diode) lamp wireless sensor device is in master-slave swap process, find that there is the information newly adding relay station, will the information of relay station be revised, and in master-slave swap activity again, transmit the information containing new relay station information in the lump.
If there is more than one solar LED (Light Emitting Diode) lamp wireless sensor device to continue the situation of noting abnormalities, those safety monitorings still can continue from node and be directly changed into host node, and other neighbouring nodes are scanned, and that continues adds different information itself and normal sensed values by acceptance write from node, and the information of continuing to send is gone out.Host node is once by selected for data write from node, and itself becomes at once from node, and stays for some time and all continue to play the part of from node for such as 60 seconds, to obtain the larger transmission capacity that continues, does not also take more host node authority.Thus, the worst situation is: if each node on bridge has data to transmit, and suppose that the distance that each node transmits is 50 meters, and the neighbor distance of each node is 1 meter, therefore first to the 50th near relay station from node, all successfully can be sent to relay station smoothly.Clearly, the distance that each node can transmit is far away, and it is shorter that abnormal data is sent to relay station required time.Node is more intensive, the situation of the damage of local detected more likely.There is a safety monitoring assembly at this every meter, when there is unusual condition, by controlling officer, can focus on easily, and in mode the most rapidly, remedy, reach and avoid safety problem to occur.

Judge that whether relay station damages, for ought finally send cannot to complete to the node of relay station, the data of relay station are transmitted, still cannot complete through three lasting trials, then can judge that relay station breaks down.In the end, through be sent to another do not have out of order relay station time, information can be passed to keyholed back plate center, and then carries out maintenance maintenance.
Transfer approach of the present utility model, obviously for partial destruction from node, also abnormal node can not be caused successfully cannot to be sent to relay station, because when having abnormal node externally to scan effectively from node, known with previous embodiment, in fact just may have 50 can select from node, so really effectively data can be sent to relay station, control center is by analytical information in addition, if certain has exception from node, node near it should have abnormal information in various degree, if circular is unmovable, also may have problem.
Without under any unusual condition, timing is carried out the operation/step of selftest by each solar LED (Light Emitting Diode) lamp wireless sensor device, as follows:
Step one, fixed cycle operator: timing usually, such as every 24 hours once, each node all will transmit the information of safety to relay station, if there is node failure, then the uploading data of relay station will have relevant information.Therefore can carry out safeguarding, repairing.For damaged node, it changes only mechanical dismounting, resets the longitude and latitude and height coordinate data, the longitude and latitude of itself and height coordinate data and related operation program that also only provide relay station.
Step 2, check and correction operation: usually, the timer of each node, all need to correct, for bridge monitoring, the timer of each node needs synchronized requirement more accurate, method is after a set time obtains the standard time by relay station via high in the clouds, the write of from node carrying out current standard time contiguous to it, what be written into the standard time afterwards changes into host node again to writing the current standard time from node near it from node, until the timer of all nodes is all updated to the current standard time, reach synchronization.
